Subject: [RFC PATCH v2 0/8] Adding the Sparx5 Switch Driver
Date: Thu, 17 Dec 2020 08:51:26 +0100 [thread overview]
Message-ID: <20201217075134.919699-1-steen.hegelund@microchip.com> (raw)
This series provides the Microchip Sparx5 Switch Driver
The Sparx5 Carrier Ethernet and Industrial switch family delivers 64
Ethernet ports and up to 200 Gbps of switching bandwidth.
It provides a rich set of Ethernet switching features such as hierarchical
QoS, hardware-based OAM and service activation testing, protection
switching, IEEE 1588, and Synchronous Ethernet.
Using provider bridging (Q-in-Q) and MPLS/MPLS-TP technology, it delivers
MEF CE
2.0 Ethernet virtual connections (EVCs) and features advanced TCAM
classification in both ingress and egress.
Per-EVC features include advanced L3-aware classification, a rich set of
statistics, OAM for end-to-end performance monitoring, and dual-rate
policing and shaping.
Time sensitive networking (TSN) is supported through a comprehensive set of
features including frame preemption, cut-through, frame replication and
elimination for reliability, enhanced scheduling: credit-based shaping,
time-aware shaping, cyclic queuing, and forwarding, and per-stream policing
and filtering.
Together with IEEE 1588 and IEEE 802.1AS support, this guarantees
low-latency deterministic networking for Fronthaul, Carrier, and Industrial
Ethernet.
The Sparx5 switch family consists of following SKUs:
- VSC7546 Sparx5-64 up to 64 Gbps of bandwidth with the following primary
port configurations:
- 6 *10G
- 16 * 2.5G + 2 * 10G
- 24 * 1G + 4 * 10G
- VSC7549 Sparx5-90 up to 90 Gbps of bandwidth with the following primary
port configurations:
- 9 * 10G
- 16 * 2.5G + 4 * 10G
- 48 * 1G + 4 * 10G
- VSC7552 Sparx5-128 up to 128 Gbps of bandwidth with the following primary
port configurations:
- 12 * 10G
- 16 * 2.5G + 8 * 10G
- 48 * 1G + 8 * 10G
- VSC7556 Sparx5-160 up to 160 Gbps of bandwidth with the following primary
port configurations:
- 16 * 10G
- 10 * 10G + 2 * 25G
- 16 * 2.5G + 10 * 10G
- 48 * 1G + 10 * 10G
- VSC7558 Sparx5-200 up to 200 Gbps of bandwidth with the following primary
port configurations:
- 20 * 10G
- 8 * 25G
In addition, the device supports one 10/100/1000/2500/5000 Mbps
SGMII/SerDes node processor interface (NPI) Ethernet port.
The Sparx5 support is developed on the PCB134 and PCB135 evaluation boards.
- PCB134 main networking features:
- 12x SFP+ front 10G module slots (connected to Sparx5 through SFI).
- 8x SFP28 front 25G module slots (connected to Sparx5 through SFI high
speed).
- Optional, one additional 10/100/1000BASE-T (RJ45) Ethernet port
(on-board VSC8211 PHY connected to Sparx5 through SGMII).
- PCB135 main networking features:
- 48x1G (10/100/1000M) RJ45 front ports using 12xVSC8514 QuadPHY’s each
connected to VSC7558 through QSGMII.
- 4x10G (1G/2.5G/5G/10G) RJ45 front ports using the AQR407 10G QuadPHY
each port connects to VSC7558 through SFI.
- 4x SFP28 25G module slots on back connected to VSC7558 through SFI high
speed.
- Optional, one additional 1G (10/100/1000M) RJ45 port using an on-board
VSC8211 PHY, which can be connected to VSC7558 NPI port through SGMII
using a loopback add-on PCB)
This series provides support for:
- SFPs and DAC cables via PHYLINK with a number of 5G, 10G and 25G
devices and media types.
- Port module configuration for 10M to 25G speeds with SGMII, QSGMII,
1000BASEX, 2500BASEX and 10GBASER as appropriate for these modes.
- SerDes configuration via the Sparx5 SerDes driver (see below).
- Host mode providing register based injection and extraction.
- Switch mode providing MAC/VLAN table learning and Layer2 switching
offloaded to the Sparx5 switch.
- STP state, VLAN support, host/bridge port mode, Forwarding DB, and
configuration and statistics via ethtool.
More support will be added at a later stage.

The series depends on the following series currently on their way
into the kernel:
- Sparx5 SerDes Driver

- Serial GPIO Controller

ChangeLog:
v2:
- The driver patch has been split into 6 patches by functionality
like this:
- the basic sparx5 driver
- hostmode with phylink support
- port module support
- switching, vlan and mactable support
- calendar bandwidth allocation support
- ethtool configuration and statistics support
- IO ranges have been collapsed into just 2 (the SerDes
driver uses the area inbetween) and the driver uses an
offset table to get the target instances.
- register macros have been converted to functions
- register_netdev() moved to the end of the switch initialization.
- sparx5_update_port_stats: use reverse christmas tree
- sparx5_get_sset_strings: copy individual strings
- sparx5_port_open: updated to better use phylink: just call
phylink_of_phy_connect directly
- sparx5_destroy_netdev: always take the NL lock
- sparx5_attr_stp_state_set: added learning state.
- sparx5_phylink_mac_config: use phylink to provide the
status for the devices phylink controls.
- sparx5_get_1000basex_status: renamed to sparx5_get_dev2g5_status
and corrected an error when combining the sync and link status
information.
- let phylink provide link status for cuPHYs and SFPs
- corrected the pause mode status handling
- use ethtool's get_link function directly
- remove the use of the phy_validate function
- sparx5_update_counter function: no longer inline
- Removed the wrapper functions around the mactable mutex
